Description

Multifunctional sound card Technical Field The invention relates to the technical field of sound cards, in particular to a multifunctional sound card. Background Conventional sound cards are not capable of perceiving a user's usage scene or sound characteristics. For example, when a user needs to switch between "male voice and female voice" or "KTV reverberation", the user needs to manually adjust a plurality of parameter knobs, and the user is completely dependent on manual mechanical operation, so that the operation is complicated, and has very large requirements on the professional performance, while some high-end models are equipped with display screens, the functions of the high-end models are usually limited to passively displaying the current Gain (Gain), equalization (EQ) or reverberation parameter states, and the high-end models lack interactivity, and cannot be used as an input end to receive a complex instruction of the user, so that when a common user faces diversified sound effect requirements, an ideal sound effect is often difficult to realize due to an excessively high operation threshold. In addition, the functional modules of the traditional sound card are relatively fixed, so that basic audio input and output and simple sound effect processing can be met, flexible expansion or customized adjustment is difficult to be carried out according to individual requirements of different users (such as sound effect fast switching of live scenes, multi-track real-time processing in music creation, intelligent background noise suppression in voice chat and the like), the use flexibility of the users is greatly limited, and the use experience of the users is reduced. Disclosure of Invention Aiming at the problems that the sound card in the prior art relies on manual mechanical operation, has complicated operation and very large requirements on the professionals, so that when a common user faces diversified sound effect requirements, the ideal sound effect is difficult to realize due to the fact that the operation threshold is too high, and the use flexibility of the user is greatly limited, the invention provides the multifunctional sound card, and solves the technical problems. The multifunctional sound card comprises a shell, an audio acquisition module, a mechanical control module, a main control module and an audio output module, wherein the audio acquisition module is arranged on the shell and used for acquiring an original audio signal, the mechanical control module is arranged on the shell and used for generating a first control signal under the operation of a user, the intelligent control module is arranged on the shell and used for generating a second control signal under the voice or touch control instruction of the user, the main control module is arranged on the shell and electrically connected with the audio acquisition module, the mechanical control module and the intelligent control module, the main control module is used for receiving the first control signal and processing the original audio signal according to the first control signal to generate a first tuning signal, the main control module is further used for receiving the second control signal and processing the original audio signal or the first tuning signal to generate a second tuning signal according to the second control signal, and the audio output module is arranged on the shell and electrically connected with the main control module and used for outputting the first tuning signal or the second tuning signal to external equipment. The multifunctional sound card has the advantages that the mechanical control module arranged on the traditional sound card is reserved, the intelligent control module which can be controlled by a voice command or a touch screen is added, for a user who is used to traditional operation, the first control signal can be generated through the knob, the key and other parts of the mechanical control module, the main control module can carry out basic processing on an original audio signal according to the first control signal, the quick adjustment requirement is met, the intelligent control module allows the user to send out a command through a voice or touch control mode to generate the second control signal, the main control module can carry out more complex and personalized signal processing on the original audio signal or the processed first tuning signal based on the command, and the double-mode combination mode not only reserves intuitiveness of traditional mechanical operation, but also introduces convenience of intelligent interaction, so that a common user can realize adjustment of diversified sound effects without professional knowledge, meanwhile, the individual requirements of live broadcast chat under different scenes such as music creation, voice and the like are met, usability and expansibility of the sound card are remarkably improved, and the use experience of the user is greatly incr
